Hello, Pjj3!!
-Genetic diversity is variability in the genetic makeup along individuals within a single species.
-Species is a group of similar organisms, and the sexually reproducing organisms they are a set of individuals that can mate/produce offspring. Everything is a part of a species. In other words, we are a part of a species because we can mate/produce offspring.
-One or more communities of different species interacting with one another and with the chemical or physical factors making up their nonliving environment.
